Try "Howards"-available in paint department at Home Depot. Use 4 "O" steel wool lightly to remove any stains and work in the polish, let stand for 15-20 minutes, then polish with clean cloth! Also good for removing the build up of grime and grease from our hands on chair arms. "Howards" has no solvents or alcohol in it (I don't think!), has a citrus smell, as it lubricates the dried wood finish. Obviously, not good for lacquered finishes.
